Unless the Pope is speaking Ex cathedra, all bets are off. I can understand respecting the office, but when the Pope jumps into the world of economics and environmentalism he's stepping way outside the bounds of infallibility.
Just because he is not speaking Ex Cathedra, doesn't give you free reign to ignore or disregard his statements. He is the Pope, afterall, in direct succession from Peter who Jesus founded the Church upon. You might want to give him a little extra credence, especially if you think you disagree with him.
Agreed. When he starts speaking the anti-war language or the Green language, he shows his "fallible" side.
No one should think another person never makes a mistake. Since the Pope influences so many he obviously has political power and one should be careful about embracing every word he says as Gospel truth IMO.
